LIPF法对甲烷空气火焰温度及OH分布场的测量
-
摘要: 介绍了激光感生预分离荧光法(LIPF)的原理及一维与二维测量实验装置。利用可调谐KrF准分子激光器，在甲烷空气火焰中测得了燃烧中间产物OH的系列荧光谱线及OH分子的二维荧光图象，对它的谱线结构进行了分析，并给出了燃烧火焰的一维温度值，测量的相对误差小于3%。二维荧光图象也定性表明燃烧火焰的OH分子密度分布和二维温度场等信息。

Abstract: The principles and the experiment for temperature and OH concentration fields measurement by LIPF is mentioned in this paper. With a tunable KrF excimer laser, the fluorescence of OH was got in a methaneair flame at the pressure of atmosphere and the structures of the spectrum were analyzed. The instantaneous temperature in the flame was also given out by LIPF, the relative error is less than 3%. The fluorescence images of OH shows the direct images of densities and the temperature fields in quality.-
